NUT-LOCK.

SPECIFICATION formingpart of Letters Patent No. 265,285, dated October 3, 1882,

I Application filed March 22, 1882. (No modeh) To all whom it may concern:

Be it known that I, SAMUEL E. SHU'rE, of Richmond, in the county of Wayne and State of Indiana, have invented a new and Improved Nut-Lock for Railroad and other Purposes, of

which the following is a specification.

The invention consists of a platewasher having a channel formed thereon as an integral part thereofor otherwise attached for the reception of a spring resting therein, having a recessed portion thereon as long as the channel in the washer-plate, the free ends of said spring each resting and bearing on nuts sufficieutly hard to prevent them from turning, but

not hard enough to prevent them from being readilyturnedtotighten,loosen,orremovethem by use of a wrench or other suitable tools.

Reference being bad to the accompanying drawings, torming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures- Figure I shows a longitudinal elevation of the nut-lock applied to the bolts. Fig. 2 is a section through the rail, showing the ends of the splice-bars,washer-plate,aud spring. Figs. 3 and 4 show side and end view of the washer plate, respectively. Fig. 5'shows a side view of the spring for holding the nuts in place.

The construction of the parts is so simple 0 that a short description will sutfice. The

washer is a double washer stamped out of a plate, and having a hook formed or struck up to receive the spring. The spring may be made of any suitable material.

As the bolts, splices, and rail have no new features in them, it will be seen that no new construction of these particulars is necessary.

The operation of this uut-lockis as follows: The bolts B B beingin place through the railand 4o splices G U, the washer-plate D is then slipped onto the bolts 13 B, as shown in Fig. 1, and v;. the nuts screwed tightly against the washer 0.1). The spring A is then driven through the channel I in the washer D andover the nuts 5 F F. The wrench is then applied and the nuts [screwed tightly to their place. The spring meanwhile presses again-st the flat sides of the nuts 1 F with suth'cient force to prevent them from turning and becoming loose, but will read ily yield suiiiciently to allow them to be turned when the wrench is applied, making it asimple and easy operation to take up the wear between any of the parts bolted together by tightening the nuts or to remove the nuts.

This nut-lock is applicable to a great many uses besides its use on railroad-tracks.

Several modifications of this invention may bemade, some of which are shown in' the drawings. Fig. 6 shows the spring held in position by a head, with a channel on the under side projecting from the splice-bar, thus dispensing with the washerplate altogether. Fig. 6 shows in side view the splice-bar in Fig. 6. Fig.

7 shows the spring fastened to the washer or splice by a pin passing through an eye in the 6 spring.

Having thus described the nature, construction, and operation of my invention, what I claim as new and useful, and desire to secure by Letters Patent, is 7o 1. The washer D, having the channel or book I formed thereon as an integral part thereof, or otherwise attached, in combination with the spring A, having the shouldered depression K, for the purposes and uses herein 7 5 described.

2. The washer D, having the channel I, and the spring A, in combination with the nuts F F, bolts B B, and parts held together by them, for the purposes and uses herein set forth.

3. The washer D, having thechannellformed thereon, in combination with the spring A, nuts F F, bolts B B, splice-bars U C, and rail E, combined and operated together forthe 8 purposes and uses herein set forth.
